Schistosoma haematobium

The pathogen in histopathogischer study, surrounded by eosinophil granulocytes

Schistosoma haematobium is a species in the genus of trematodes.

The pathogen can cause the person responsible for numerous deaths infectious disease schistosomiasis, especially in Africa.

The adult organisms are found in veins that surround the bladder. There they produce eggs through the bladder wall and call forth hematuria in urine. In the bladder, too much calcium stores a, resulting in hydronephrosis result.

In contaminated water swim the cercariae and penetrate through the skin into the blood system of the patients. In the liver, then be adult flukes from it. These have external antigens of the host, so they escape the immune system. The eggs come with micturition in the waters in the vicinity of settlements. There are several eggs forming a miracidium that infects a Bulinus snail as an intermediate host, where the epithelium is stripped and a sporocyst arises. Within a few weeks of it developing daughter sporocysts, which soon leave the snails and then are infective to hosts in the water again.

To diagnose the urine is examined, the eggs are approximately 112-180 × 40-70 microns in size. For prevention, the basic rules of hygiene should be observed. For treatment of praziquantel comes in wondering if it is available.
